Ford Fiesta Heater Control Valve

[SeymourBush]

Hi - I may have to replace the heater control on my Ford Fiesta - apparently it's a 15 minute job... ...but... ...do I have to drain the coolant before doing the job? Haynes manual says yes - but repair hints on the net don't mention draining. So - do I or don't I?

Thanks - Seymour Bush

if you undo the valve,what do you think will come out,of course water.speaksv for itself,haynes dont tell you things for the fun of it.

To add to Norms answer, make sure you do this with a COLD ENGINE. Haynes do not tell you that you will be scalded if repairs to the valve are done on a hot engine.

clamp both hoses with small g clamps or suchlike then you won't lose any coolant whilst changing the valve..simple really!

Will try nipping the tubes - thanks

Hi just replaced on this morning. It didn't require the system to be drained but make sure you do it when engine is cold as some water does come out. Took about 15minutes in all.
